This challenging worksheet, Even and Odd Puzzles, asks second graders to reason about parity rather than just spot it. Four multiple-choice items pick the all-odd pair (11 and 23), explain that even plus odd is always odd, finish the skip-counting pattern 5, 10, 15, 20, ___, and decide whether Sarah can split 27 beads into two equal groups.
Five fill-ins push further: the sum of 13 and 15, the largest even number less than 50, how many odd numbers live between 30 and 40, and why doubling any whole number always produces an even result, locking in habits that lead straight into multiplication.
